### Ubuntu Server 16.04 配置静态ip及动态ip ###

#### 首先把需要用的指令列出 ####

查看当前网路配置

ifconfig

查看设备拥有的网卡

ip addr
    # ip link

查看当前连接商在网卡情况

ip route show
    
    default via 192.168.1.1 dev eth0
    192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.110
    192.168.1.0/24 dev eth1  proto kernel  scope link  src 192.168.1.200

重启网络命令

systemctl restart networking
    # or
    # service networking restart

#### 要用到关键配置文件列出 ####

网卡配置地址  
`/etc/network/interfaces`

内容大概是这样的

# This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).
    
    source /etc/network/interfaces.d/*
    
    # The loopback network interface
    auto lo
    iface lo inet loopback
    
    auto eth0
    #iface eno1 inet dhcp
    iface eth0 inet static
    address 192.168.1.119
    netmask 255.255.255.0
    getway 192.168.1.1
    dns-nameserver 1.1.1.1
    dns-nameserver 114.114.114.114
    dns-nameserver 8.8.8.8

DNS配置地址  
`/etc/resolv.conf`  
内容大概如下

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
    # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
    nameserver 0.0.0.0
    nameserver 8.8.8.8

`/etc/resolv.conf`修改在内容将会立即生效，但是一旦重启电脑或网络又会被重置。

通过修改`/etc/resolvconf/resolv.conf.d/base`配置文件，再重启networking可永久生效

#### 配置静态或动态IP ####

首先需要先查看网卡的名称

ip router show

进入网络配置文件进行修改配置

sudo vi /etc/network/interfaces

配置文件如下

auto eth0
    iface eth0 inet dhcp		# 动态配置
    
    
    auto eth1
    iface eth1 inet static 		# 配置静态
    address 192.168.1.100  		# ip地址 
    netmask 255.255.255.0  		# 网络掩码
    gateway 192.168.1.1    		# 网关
    dns-nameserver 114.114.114.114  # dns服务器,可以设置多个

重启网络

sudo service networking restart

查看当前ip

ifconfig
